GROUNDING ThE GENERATOR
A grounding nut (X, Fig. 3) is supplied
with the generator for use when required
by local electrical ordinances. Your
local electric company or a certified
electrician should be able to help you
with this information.
USE OF ExTENSION CORDS
WARNING: Use only grounded
extension cords. Use only three wire or
double-insulated power tools.
Only use grounded extension cords
that are rated for outdoor use and
equipment with a third-wire ground. It
is recommended that GFCI protected
spider box or inline GFCI adapter are
used when connecting to any of the
generator’s receptacles.
When a long extension cord is used
to connect an appliance or tool to the
generator, a voltage drop occurs. The
longer the cord, the greater the voltage
drop. This results in less voltage being
supplied to the appliance or tool and
increases the amount of current (amp)
draw or reduces performance. A heavier
cord with a larger wire size will reduce
the voltage drop. Be sure to choose a
cord that will supply enough voltage
to operate your tool or appliance. The
tables indicate appropriate gauge for
extension cords and the voltage drop
caused by the use of extension cords,
given different electrical loads.
CAUTION: Operating equipment at
low voltage can cause it to overheat.
Using an excessively long extension cord
can cause the cord to overheat.
WARNING: Keep electrical cords in
good condition. Do not use worn, bare
or frayed cords because they can cause
electrical shock.
